Twisted Core 10.1.0 (2010-06-27)
================================
Features
--------
- Add linux inotify support, allowing monitoring of file system
events. (#972)
- Deferreds now support cancellation. (#990)
- Added new "endpoint" interfaces in twisted.internet.interfaces,
which abstractly describe stream transport endpoints which can be
listened on or connected to. Implementations for TCP and SSL
clients and servers are present in twisted.internet.endpoints.
Notably, client endpoints' connect() methods return cancellable
Deferreds, so code written to use them can bypass the awkward
"ClientFactory.clientConnectionFailed" and
"Connector.stopConnecting" methods, and handle errbacks from or
cancel the returned deferred, respectively. (#1442)
- twisted.protocols.amp.Integer's documentation now clarifies that
integers of arbitrary size are supported and that the wire format
is a base-10 representation. (#2650)
- twisted.protocols.amp now includes support for transferring
timestamps (amp.DateTime) and decimal values (amp.Decimal). (#2651)
- twisted.protocol.ftp.IWriteFile now has a close() method, which can
return a Deferred. Previously a STOR command would finish
immediately upon the receipt of the last byte of the uploaded file.
With close(), the backend can delay the finish until it has
performed some other slow action (like storing the data to a
virtual filesystem). (#3462)
- FilePath now calls os.stat() only when new status information is
required, rather than immediately when anything changes. For some
applications this may result in fewer stat() calls. Additionally,
FilePath has a new method, 'changed', which applications may use to
indicate that the FilePath may have been changed on disk and
therefore the next status information request must fetch a new
stat result. This is useful if external systems, such as C
libraries, may have changed files that Twisted applications are
referencing via a FilePath. (#4130)
- Documentation improvements are now summarized in the NEWS file.
(#4224)
- twisted.internet.task.deferLater now returns a cancellable
Deferred. (#4318)
- The connect methods of twisted.internet.protocol.ClientCreator now
return cancellable Deferreds. (#4329)
- twisted.spread.pb now has documentation covering some of its
limitations. (#4402)
- twisted.spread.jelly now supports jellying and unjellying classes
defined with slots if they also implement __getstate__ and
__setstate__. (#4430)
- twisted.protocols.amp.ListOf arguments can now be specified as
optional. (#4474)
Bugfixes
--------
- On POSIX platforms, reactors now support child processes in a way
which doesn't cause other syscalls to sometimes fail with EINTR (if
running on Python 2.6 or if Twisted's extension modules have been
built). (#733)
- Substrings are escaped before being passed to a regular expression
for searching to ensure that they don't get interpreted as part of
the expression. (#1893)
- twisted.internet.stdio now supports stdout being redirected to a
normal file (except when using epollreactor). (#2259)
- (#2367)
- The tap2rpm script now works with modern versions of RPM. (#3292)
- twisted.python.modules.walkModules will now handle packages
explicitly precluded from importing by a None placed in
sys.modules. (#3419)
- ConnectedDatagramPort now uses stopListening when a connection
fails instead of the deprecated loseConnection. (#3425)
- twisted.python.filepath.FilePath.setContent is now safe for
multiple processes to use concurrently. (#3694)
- The mode argument to the methods of
twisted.internet.interfaces.IReactorUNIX is no longer deprecated.
(#4078)
- Do not include blacklisted projects when generating NEWS. (#4190)
- When generating NEWS for a project that had no significant changes,
include a section for that project and say that there were no
interesting changes. (#4191)
- Redundant 'b' mode is no longer passed to calls to FilePath.open
and FilePath.open itself now corrects the mode when multiple 'b'
characters are present, ensuring only one instance of 'b' is
provided, as a workaround for http://bugs.python.org/issue7686.
(#4207)
- HTML tags inside <pre> tags in the code snippets are now escaped.
(#4336)
- twisted.protocols.amp.CommandLocator now allows subclasses to
override responders inherited from base classes. (#4343)
- Fix a bunch of small but important defects in the INSTALL, README
and so forth. (#4346)
- The poll, epoll, glib2, and gtk2 reactors now all support half-
close in the twisted.internet.stdio.StandardIO transport. (#4352)
- twisted.application.internet no longer generates an extra and
invalid entry in its __all__ list for the nonexistent
MulticastClient. (#4373)
- Choosing a reactor documentation now says that only the select-
based reactor is a truly cross-platform reactor. (#4384)
- twisted.python.filepath.FilePath now no longer leaves files open,
to be closed by the garbage collector, when an exception is raised
in the implementation of setContent, getContent, or copyTo. (#4400)
- twisted.test.proto_helpers.StringTransport's getHost and getPeer
methods now return IPv4Address instances by default. (#4401)
- twisted.protocols.amp.BinaryBoxProtocol will no longer deliver an
empty string to a switched-to protocol's dataReceived method when
the BinaryBoxProtocol's buffer happened to be empty at the time of
the protocol switch. (#4405)
- IReactorUNIX.listenUNIX implementations now support abstract
namespace sockets on Linux. (#4421)
- Files opened with FilePath.create() (and therefore also files
opened via FilePath.open() on a path with alwaysCreate=True) will
now be opened in binary mode as advertised, so that they will
behave portably across platforms. (#4453)
- The subunit reporter now correctly reports import errors as errors,
rather than by crashing with an unrelated error. (#4496)
Improved Documentation
----------------------
- The finger tutorial example which introduces services now avoids
double-starting the loop to re-read its users file. (#4420)
- twisted.internet.defer.Deferred.callback's docstring now mentions
the implicit chaining feature. (#4439)
- doc/core/howto/listing/pb/chatclient.py can now actually send a
group message. (#4459)
Deprecations and Removals
-------------------------
- twisted.internet.interfaces.IReactorArbitrary,
twisted.application.internet.GenericServer, and
twisted.application.internet.GenericClient are now deprecated.
(#367)
- twisted.internet.gtkreactor is now deprecated. (#2833)
- twisted.trial.util.findObject has been deprecated. (#3108)
- twisted.python.threadpool.ThreadSafeList is deprecated and Jython
platform detection in Twisted core removed (#3725)
- twisted.internet.interfaces.IUDPConnectedTransport has been removed
(deprecated since Twisted 9.0). (#4077)
- Removed twisted.application.app.runWithProfiler, which has been
deprecated since Twisted 8.0. (#4090)
- Removed twisted.application.app.runWithHotshot, which has been
deprecated since Twisted 8.0. (#4091)
- Removed twisted.application.app.ApplicationRunner.startLogging,
which has been deprecated (doesn't say since when), as well as
support for the legacy
twisted.application.app.ApplicationRunner.getLogObserver method.
(#4092)
- twisted.application.app.reportProfile has been removed. (#4093)
- twisted.application.app.getLogFile has been removed. (#4094)
- Removed twisted.cred.util.py, which has been deprecated since
Twisted 8.3. (#4107)
- twisted.python.util.dsu is now deprecated. (#4339)
- In twisted.trial.util: FailureError, DirtyReactorWarning,
DirtyReactorError, and PendingTimedCallsError, which have all been
deprecated since Twisted 8.0, have been removed. (#4505)

Features
--------
- The twistd man page now has a SIGNALS section. (#689)
- reactor.spawnProcess now will not emit a PotentialZombieWarning
when called before reactor.run, and there will be no potential for
zombie processes in this case. (#2078)
- High-throughput applications based on Perspective Broker should now

be composed with some other argument types to create a zero or more
element sequence of that type. (#4116)
- If returnValue is invoked outside of a function decorated with
@inlineCallbacks, but causes a function thusly decorated to exit, a
DeprecationWarning will be emitted explaining this potentially
confusing behavior. In a future release, this will cause an
exception. (#4157)
- twisted.python.logfile.BaseLogFile now has a reopen method allowing
you to use an external logrotate mechanism. (#4255)
Bugfixes
--------
- FTP.ftp_NLST now handles requests on invalid paths in a way
consistent with RFC 959. (#1342)
- twisted.python.util.initgroups now calls the low-level C initgroups
by default if available: the python version can create lots of I/O

fixing a terrible infinite recursion bug that's only on edge case.
(#3289)

calculating the length so that the calculated length is equal to
the actual length of the transported data. (#3299)
- twisted.python.win32.cmdLineQuote now correctly quotes empty
strings arguments (#3876)
- Change the behavior of the Gtk2Reactor to register only one source
watch for each file descriptor, instead of one for reading and one

- Twisted Trial no longer crashes if it can't remove an old
_trial_temp directory. (#4020)
- The optional _c_urlarg extension now handles unquote("") correctly
on platforms where malloc(0) returns NULL, such as AIX. It also
compiles with less warnings. (#4142)
- On POSIX, child processes created with reactor.spawnProcess will no
longer automatically ignore the signals which the parent process
has set to be ignored. (#4199)
- All SOCKSv4a tests now use a dummy reactor with a deterministic
resolve method. (#4275)

- The HTTP proxy will no longer pass on keep-alive request headers
from the client, preventing pages from loading then "hanging"
(leaving the connection open with no hope of termination). (#4179)

microdom's methods in general should now issue more meaningful exceptions
when invalid parameters are passed (#3421)
- WSGI applications will no longer have spurious Content-Type headers added to
their responses by the twisted.web server. In addition, WSGI applications
will no longer be able to specify the server-restricted headers Server and
Date (#3569)
- http_headers.Headers now normalizes the case of raw headers passed directly
to it in the same way that it normalizes the headers passed to setRawHeaders
(#3557)
- The distrib module no longer relies on the deprecated woven package (#3559)
- twisted.web.domhelpers now works with both microdom and minidom (#3600)
- twisted.web servers will now ignore invalid If-Modified-Since headers instead
of returning a 500 error (#3601)
- Certain request-bound memory and file resources are cleaned up slightly
sooner by the request when the connection is lost (#1621, #3176)
- xmlrpclib.DateTime objects should now correctly round-trip over twisted.web's
XMLRPC support in all supported versions of Python, and errors during error
serialization will no longer hang a twisted.web XMLRPC response (#2446)
- request.content should now always be seeked to the beginning when
request.process is called, so application code should never need to seek
back manually (#3585)
- Fetching a child of static.File with a double-slash in the URL (such as
"example//foo.html") should now return a 404 instead of a traceback and
500 error (#3631)
- downloadPage will now fire a Failure on its returned Deferred instead of
indicating success when the connection is prematurely lost (#3645)
- static.File will now provide a 404 instead of a 500 error when it was
constructed with a non-existent file (#3634)
- microdom should now serialize namespaces correctly (#3672)
- The HTTP Auth support resource wrapper should no longer corrupt requests and
cause them to skip a segment in the request path (#3679)
- The twisted.web WSGI support should now include leading slashes in PATH_INFO,
and SCRIPT_NAME will be empty if the application is at the root of the
resource tree. This means that WSGI applications should no longer generate
URLs with double-slashes in them even if they naively concatenate the values
(#3721)
- WSGI applications should now receive the requesting client's IP in the
REMOTE_ADDR environment variable (#3730)
- The distrib module should work again. It was unfortunately broken with the
refactoring of twisted.web's header support (#3697)
- static.File now supports multiple ranges specified in the Range header
(#3574)
- static.File should now generate a correct Content-Length value when the
requested Range value doesn't fit entirely within the file's contents (#3814)
- Attempting to call request.finish() after the connection has been lost will
now immediately raise a RuntimeError (#4013)
- An HTTP-auth resource should now be able to directly render the wrapped
avatar, whereas before it would only allow retrieval of child resources
(#4014)
- twisted.web's wsgi support should no longer attempt to call request.finish
twice, which would cause errors in certain cases (#4025)
- WSGI applications should now be able to handle requests with large bodies
(#4029)
- Exceptions raised from WSGI applications should now more reliably be turned
into 500 errors on the HTTP level (#4019)
- DeferredResource now correctly passes through exceptions raised from the
wrapped resource, instead of turning them all into 500 errors (#3932)
- Agent.request now generates a Host header when no headers are passed at
(#4131)
Deprecations and Removals
-------------------------
- The unmaintained and untested twisted.web.monitor module was removed (#2763)
- The twisted.web.woven package has been removed (#1522)
- All of the error resources in twisted.web.error are now in
twisted.web.resource, and accessing them through twisted.web.error is now
deprecated (#3035)
- To facilitate a simplification of the timeout logic in server.Session,
various things have been deprecated (#3457)
- the loopFactory attribute is now ignored
- the checkExpired method now does nothing
- the lifetime parameter to startCheckingExpiration is now ignored
- The twisted.web.trp module is now deprecated (#2030)

Twisted Words 9.0.0 (2009-11-24)
================================
Features
--------
- IRCClient.describe is a new method meant to replace IRCClient.me to send
CTCP ACTION messages with less confusing behavior (#3910)
- The XMPP client protocol implementation now supports ANONYMOUS SASL
authentication (#4067)
- The IRC client protocol implementation now has better support for the
ISUPPORT server->client message, storing the data in a new
ServerSupportedFeatures object accessible via IRCClient.supported (#3285)
Fixes
-----
- The twisted.words IRC server now always sends an MOTD, which at least makes
Pidgin able to successfully connect to a twisted.words IRC server (#2385)
- The IRC client will now dispatch "RPL MOTD" messages received before a
"RPL MOTD START" instead of raising an exception (#3676)
- The IRC client protocol implementation no longer updates its 'nickname'
attribute directly; instead, that attribute will be updated when the server
acknowledges the change (#3377)
- The IRC client protocol implementation now supports falling back to another
nickname when a nick change request fails (#3377, #4010)
Deprecations and Removals
-------------------------
- The TOC protocol implementation is now deprecated, since the protocol itself
has been deprecated and obselete for quite a long time (#3580)
- The gui "im" application has been removed, since it relied on GTK1, which is
hard to find these days (#3699, #3340)

Core 8.2.0 (2008-12-16)
=======================
Features
--------
- Reactors are slowly but surely becoming more isolated, thus improving
testability (#3198)
- FilePath has gained a realpath method, and FilePath.walk no longer infinitely
recurses in the case of a symlink causing a self-recursing filesystem tree
(#3098)
- FilePath's moveTo and copyTo methods now have an option to disable following
of symlinks (#3105)
- Private APIs are now included in the API documentation (#3268)
- hotshot is now the default profiler for the twistd --profile parameter and
using cProfile is now documented (#3355, #3356)
- Process protocols can now implement a processExited method, which is
distinct from processEnded in that it is called immediately when the child
has died, instead of waiting for all the file descriptors to be closed
(#1291)
